Nexus Blitz FPS

So yesterday I played Nexus Blitz and my Frames were fine. And it was pretty fun! But then today I went onto PBE to play some more and for some reason while i'm in game. I'm having FPS problems. It feels like my FPS is at 30. But when I go and check on the top right of the screen it says there at 150. So i'm wondering whats going on at this point. So I ask my team if they are having same problem and they are. I also ask on all chat, and they also are. So i'm not sure if this problem is riot or my PC. But i'm pretty sure its not my PC since it ran fine before. And i'm not sure if this happens in Summoners Rift. {{sticker:slayer-jinx-unamused}}
